Definitions

  • the present invention relates to agricultural harvesters, and, more specifically to tailings processors in the grain cleaning system of agricultural harvesters.
  • a combine An agricultural harvester known as a "combine” is historically termed such because it combines multiple harvesting functions with a single harvesting unit, such as picking, threshing, separating, and cleaning.
  • a combine includes a header which removes the crop from a field, and a feeder housing which transports the crop matter into a threshing rotor.
  • the threshing rotor rotates within a perforated housing, which may be in the form of adjustable concaves, and performs a threshing operation on the crop to remove the grain.
  • Once the grain is threshed it falls through perforations in the concaves onto a grain pan. From the grain pan the grain is cleaned using a cleaning system, and is then transported to a grain tank onboard the combine.
  • a cleaning fan blows air through the sieves to discharge chaff and other debris toward the rear of the combine.
  • Non-grain crop material such as straw from the threshing section proceeds through a residue handling system, which may utilize a straw chopper to process the non-grain material and direct it out the rear of the combine.
  • a residue handling system which may utilize a straw chopper to process the non-grain material and direct it out the rear of the combine.
  • the combine When the grain tank becomes full, the combine is positioned adjacent a vehicle into which the grain is to be unloaded, such as a semi-trailer, gravity box, straight truck, or the like, and an unloading system on the combine is actuated to transfer the grain into the vehicle.
  • a rotary threshing or separating system includes one or more rotors that can extend axially (front to rear) or transversely (side to side) within the body of the combine, and which are partially or fully surrounded by perforated concaves.
  • the crop material is threshed and separated by the rotation of the rotor within the concaves.
  • Coarser non-grain crop material such as stalks and leaves pass through a straw beater to remove any remaining grains, and then are transported to the rear of the combine and discharged back to the field.
  • the separated grain, together with some finer non-grain crop material such as chaff, dust, straw, and other crop residue are discharged through the concaves and fall onto a grain pan where they are transported to a cleaning system.
  • the grain and finer non-grain crop material may also fall directly onto the cleaning system itself.
  • a cleaning system further separates the grain from non-grain crop material, and typically includes a fan directing an airflow stream upwardly and rearwardly through vertically arranged sieves which oscillate in a fore and aft manner.
  • the airflow stream lifts and carries the lighter non-grain crop material towards the rear end of the combine for discharge to the field.
  • Grain and non-grain crop material remaining on the upper and lower sieves are physically separated by the reciprocating action of the sieves as the material moves rearwardly. Any grain and/or non-grain crop material which passes through the upper sieve, but does not pass through the lower sieve, is directed to a tailings pan. Grain falling through the lower sieve lands on a bottom pan of the cleaning system, where it is conveyed forwardly toward a clean grain auger.
  • the clean grain auger conveys the grain to a grain elevator, which transports the grain upwards to a grain tank for temporary storage.
  • the grain accumulates to the point where the grain tank is full and is discharged to an adjacent vehicle such as a semi trailer, gravity box, straight truck or the like by an unloading system on the combine that is actuated to transfer grain into the vehicle.
  • tailings may include incompletely threshed or unthreshed crop, free grains of completely threshed crop, and other plant material or Material Other than Grain (MOG).
  • MOG Material Other than Grain
  • a return auger or tailings conveyance receives the tailings from a tailings auger at the forward end of the auger pan, and lifts the tailings vertically in order to recycle the tailings through the threshing and separating or cleaning system.
  • a tailings processor may be provided, which functions to further thresh the tailings before they are returned to the cleaning system.
  • the aggressiveness of the tailings processor is controlled by increasing or decreasing the radial or threshing clearance between the rasps on the rotating drum of the tailings processor and a portion of the cylindrical housing, typically the housing floor.
  • Different crops and different harvest conditions require different levels of tailings processor aggressiveness in order to effectively re-thresh the tailings that have passed through the cleaning system.
  • determining and optimizing the effectiveness of the tailings processor was often a cumbersome process of trial and error, involving visually inspecting the output of the tailings processor or the grain in the grain tank of the combine, and manually adjusting the radial or threshing clearance of the tailings processor, such manual adjustment being involved and time-consuming.
  • U.S. Patent No. 3,247,855 teaches manually adjusting the running clearance between the impeller blades and the wall of a tailings unit mounted at the top of a tailings conveyance that returns tailings to the cleaning system.
  • the running clearance is adjusted using eccentric blocks that mount the axle of the impeller, and with a handle connected thereto that has preset positions.
  • E.P. Patent No. 2,064,941 similarly teaches manually adjusting the running clearance between the impeller blades and a wall of the rethreshing housing using an adjustable wall.
  • WO 2009034442A2 similarly teaches a rethreshing housing located at the top of the return auger that delivers tailings back to the cleaning system, wherein the rethreshing concave is manually adjusted using screw threads.
  • U.S. Patent No. 6,342,006 teaches using a kernel counting sensor to determine how much grain is passing back to the primary threshing system of the combine, and then adjusting the settings of this primary threshing system.
  • a sieve on an output auger of the tailings elevator or auger conveyer is adjustable to control the dropping of grain on the kernel counting sensor, but the aggressiveness of a tailings processor is not automatically adjusted, no separate tailings processor being provided.
  • U.S. Patent No. 4,348,855 teaches a sieve system at the top of the grain elevator of the combine that determines the ratio of damaged to undamaged grain by separating the damaged grain, which subsequently impacts a transducer. The system then varies the speed of the primary threshing rotor to minimize grain damage while operating at the highest rotor speed that will work. However, no tailings processor is involved.
  • U.S. Published Application No. 20030216159 teaches a tool for removing the threshing concaves of a transverse rotor combine. A concave adjustment mechanism is provided using one or more actuators. However, again, this adjustment is to the concaves of the primary threshing and separating system, not to the aggressiveness of a tailings processor.
  • U.S. Published Application No. teaches a concave of a main transverse threshing rotor that has a hinged end portion with a bridging device between the hinged end portion and the remainder of the threshing system.
  • this adjustment is to the concaves of the primary threshing and separating system, not to the aggressiveness of a tailings processor.
  • U.S. Published Application No. 20150009328 discloses a combine harvester with a control arrangement including an optical sensor device for recording image series of a continuous main crop stream. Based on the recorded images a portion of damaged grain and a portion of non-grain in the main crop stream are ascertained and visualized on a display device.
  • the present invention provides such a way to optimize the effectiveness of the tailings processor.
  • Embodiments of the present invention are implemented on the tailings processor that functions to further thresh tailings before they are recycled through the cleaning system of the agricultural harvester.
  • the tailings processor may be provided with rasps on a rotating drum rotating within a cylindrical housing.
  • the cylindrical housing has a housing floor, which may or may not be provided with lugs in order to further enhance the threshing action of the tailings processor.
  • a sensor or grain camera may be attached to the outlet of the grain elevator of the combine, or to the cylindrical housing of the tailings processor, or elsewhere in the cleaning system or subsequent grain handling machinery of the combine, in order to determine the effectiveness of the further threshing of the tailings.
  • the information provided by the sensor or grain camera is used to adjust the aggressiveness of the tailings processor in order to optimize the re-threshing of the tailings.
  • the rasps of the rotating drum pass within a radial or threshing clearance of the housing floor of the tailings processor as the rotating drum turns.
  • the aggressiveness of the tailings processor is largely controlled by varying this radial or threshing clearance. Different crops and different harvest conditions require different levels of tailings processor aggressiveness in order to effectively re-thresh the tailings that have passed through the cleaning system. Specifically, if too many pods, ears, or spikes of unthreshed grain pass through the tailings processor, then it is necessary to reduce the radial or threshing clearance in order to increase the tailings processor aggressiveness.
  • Adjusting mechanisms are operable to increase or decrease the radial or threshing clearance by lowering or raising a housing floor of the cylindrical housing of the tailings processor, using one or more actuators.
  • the sensor or grain camera which is connected to a control system or controller, cooperates with the control system or controller in order to determine if too many pods, ears, or spikes of unthreshed grain are passing through the tailings processor, or if too much grain or too many kernels are being broken in the tailings processor. If the control system or controller determines in cooperation with the sensor or grain camera that too many pods, ears, or spikes of unthreshed grain are passing through the tailings processor, then it determines that it is necessary to reduce the radial or threshing clearance in order to increase the tailings processor aggressiveness. The controller or control system then raises the housing floor using adjusting mechanisms.
  • control system or controller again cooperates with the sensor or grain camera to determine if too many pods, ears, or spikes of unthreshed grain are still passing through the tailings processor, or if too much grain or too many kernels are now being broken in the tailings processor, and makes further adjustment to the radial or threshing clearance as necessary, in closed loop fashion and in real time.
  • control system or controller determines in cooperation with the sensor or grain camera that too much grain or too many kernels are being broken in the tailings processor, then it determines that it is necessary to increase the radial or threshing clearance in order to decrease the tailings processor aggressiveness.
  • the controller or control system then lowers the housing floor using adjusting mechanisms. Again, following this adjustment, the control system or controller once more cooperates with the sensor or grain camera to determine if too much grain or too many kernels are still being broken in the tailings processor, or if too many pods, ears, or spikes of unthreshed grain are now passing through the tailings processor, and makes further adjustment to the radial or threshing clearance as necessary, in closed loop fashion and in real time.
  • An indicator or indicators may be connected to one or to each of the adjusting mechanisms in order to give visual feedback on the current amount of radial or threshing clearance to an operator conducting a visual inspection.
  • feedback may be provided to the operator in the operator cab of the combine by way of a gauge or other visual or audio device, or by way of an electronic yield monitor device.
  • the sensor or grain camera is capable and operates to image grain having been re-threshed by the tailings processor.
  • the sensor or grain camera may be a digital camera producing digital images that are subsequently processed by the controller or control system.
  • the sensor or grain camera may be another type of sensor with imaging capabilities, such as ultrasound, thermal or infrared imaging, or radar imaging, as non-limiting examples.
  • the senor or grain camera operates to identify in the grain sample unthreshed grain pods, ears, and spikes, and to identify in the grain sample broken grain.
  • the controller or control system uses this information to increase or decrease the radial or threshing clearance in order to decrease or increase, respectively, the tailings processor aggressiveness in closed loop fashion and in real time, as described above.
  • the sensor or grain camera may be located upon the outlet of the grain elevator, upon the cylindrical housing of the tailings processor, or elsewhere within the cleaning system, grain elevator, grain tank, or even on the unloading conveyance, provided that at least a portion of the grain sample at that location has previously passed through the tailings processor as tailings.
  • Other such locations where a sensor or grain camera according to an embodiment of the invention may be located include upon the front or rear surface of the tailings processor, attached to the return auger, attached to the bottom pan of the cleaning system, or attached to the clean grain auger, as non-limiting examples.
  • the invention in one form is directed to a system for controlling the aggressiveness of a tailings processor in an agricultural harvester.
  • the agricultural harvester has a threshing and separating system, a grain cleaning system, a tailings auger and a return auger, a clean grain auger, a grain elevator having an outlet, and a grain tank.
  • the tailings processor functions to re-threshing tailings received from the grain cleaning system.
  • the tailings processor is engaged with the tailings auger and with the return auger, and has a rotating threshing device within a housing.
  • the system is provided with at least one imaging device oriented to image a grain sample, at least a portion of which has at least once passed through the tailings processor.
  • the system is further provided with a controller or control system connected to the imaging device.
  • the tailings processor is provided with an arrangement to automatically adjust the aggressiveness of the tailings processor, which is connected to and controlled by the controller or control system.
  • the controller or control system is configured to automatically adjust the aggressiveness of the tailings processor using the arrangement, based on information provided by the at least one imaging device.
  • the invention in another form is directed to an agricultural harvester including a chassis, a threshing and separating system carried by the chassis for separating grain from material other than grain, a cleaning system receiving grain from the threshing and separating system for further cleaning the grain, a tailings processor receiving tailings from the cleaning system, and a system for controlling the aggressiveness of the tailings processor.
  • the agricultural harvester further has a tailings auger and a return auger, a clean grain auger, a grain elevator having an outlet, and a grain tank.
  • the tailings processor functions to re-thresh tailings received from the grain cleaning system.
  • the tailings processor is engaged with the tailings auger and with the return auger, and has a rotating threshing device within a housing.
  • the system for controlling the aggressiveness of the tailings processor is provided with at least one imaging device oriented to image a grain sample, at least a portion of which has at least once passed through the tailings processor.

  • the controller or control system is configured to automatically adjust the aggressiveness of the tailings processor using the arrangement, based on information provided by the at least one imaging device.
  • An advantage of the present invention is that it automatically optimizes the effectiveness of the tailings processor, so that a minimum of unthreshed grain or broken grain is delivered to the grain tank. Another advantage is that operation of the present invention is largely automatic, requiring a minimum of trial and error, and physical effort, on the part of the operator of the agricultural harvester.
  • ground refers to that part of the crop material that is threshed and separated from the discardable part of the crop material, which is referred to as non-grain crop material, MOG or straw.
  • Incompletely threshed crop material which may include unthreshed crop, free grains of completely threshed crop, and other Material Other than Grain (MOG), is referred to as "tailings".

  • the sensor or grain camera 90a may make such determination and transmit a signal to the controller 106 indicating the determination so that the controller 106 may control the actuators 92a and 92b accordingly.
  • the method 900 begins with a Step 910 of setting a standard clearance 88 by extending or contracting the actuators 92a, 92b.

  • Such selection is transmitted to the controller 106, which receives it in the Step 910 and based upon the inputted or selected standard clearance 88, the controller 106 commands the actuators 92a, 92b to extend or contract to achieve the clearance 88 which is standard for the crop.
  • the controller 106 also receives an indication of a desired level of broken grain and/or unthreshed grain from the user. Such level may be low, medium, or high.

  • a Step 930 either the grain camera 90a, 90b or the processor 106 processes the image data, depending on which embodiment of processing is implemented. Based on the processed image data, either the grain camera 90a, 90b or the processor 106 calculates the broken grain and unthreshed grain content from the image data, Step 940. In an exemplary embodiment either the grain camera 90a, 90b or the processor 106 calculates the broken grain and unthreshed grain content as low, medium, or high.
  • the grain camera 90a, 90b or the processor 106 compares these amounts, e.g., low, medium, and high, to desired amounts, e.g., low, medium, or high, inputted by the user in the Step 910 to determine whether too much grain or too many kernels are still being broken in the tailings processor 80, or whether too many pods, ears, or spikes of unthreshed grain are now passing through the tailings processor 80 in the Step 940. Based on the determination made in the Step 940, the processor 106 commands the actuators 92a, 92b to extend or contract to achieve a desired clearance 88 to bring the calculated broken grain content and unthreshed content to its desired level input by the user in the Step 910. The method 900 then returns to the Step 920 to repeat the foregoing process.
